The Geissele Super Modular Rail MK14 M-LOK free float AR-15 handguard puts serious mounting real estate in your hands without the bulk. Built from lightweight 6061 T6 aluminum and finished with Type III hardcoat anodize, this handguard delivers the accuracy advantage of barrel free-floating while keeping your setup svelte enough for rail covers, vertical grips, and thumb-over-the-bore support techniques. Whether you're running a precision rifle, a duty gun, or a versatile do-everything AR, the MK14's balanced design gives you all the modularity of a full-size quad rail without the weight penalty.
M-LOK slots run the full length of the handguard at the 3, 6, and 9 o'clock positions, giving you flexible real estate for lights, lasers, bipods, and other accessories exactly where you need them. An uninterrupted Picatinny rail spans the top for optics mounting or additional accessories, and thoughtfully placed QD pushbutton sling swivel sockets at 11 and 1 o'clock keep your attachment points tidy and within reach.
The free-float system uses Geissele's proprietary barrel nut—a 2.25" length design that anchors your barrel straight and rigid for the consistency that matters downrange. Installation is straightforward, and the design isolates your barrel from handguard pressure so accuracy isn't compromised by mounting or grip pressure. Available in classic Black or Geissele's Desert Dirt Color (DDC) to match your rifle's aesthetic.
